The purpose of the this kind grinding mills are to grind non-flammable andnon-explosive materials in the fields of building materials, mining, metallurgies and chemical industry with hardness less than9.3 in Moh’s scale and humidity less than 6 percent. Examples of the materials are: quartz, feldspar, barite, fluorite, dolomite,garnet, bauxite, zircon, marble, calcite, iron ore, rock phosphate, coal, slag and so on(400 kinds of material). The granularity ofthe final products can be changed from 30 to 425 meshes. But do you know the problems of traditional Raymond mill?

Raymond mill is a kind of widely used and mines, cement plants, chemical grinding equipment, is one of the important equipment for deep processing of non-metallic minerals. Because of Raymond mill stable performance, strong adaptability, cost-effective, in more than 20 years since the introduction of China, has been popular used in the processing of non-metallic minerals.However, the application of nonmetallic minerals in the ultrafine powder of extensive development, downstream enterprises more and more high to the requirement of non-metallic minerals. Especially for product fineness had higher requirements.This makes the traditional Raymond mill ragged.The problems of traditional Raymond mill has been plagued by mineral processing enterprises and equipment manufacturers. These problems mainly displays in:

2. The high mechanical failure rate, big power consumption, noise, and exhaust emissions

3. Low system efficiency, the product collection system of the separation effect is not ideal, a large number of fine powder can not get effective collected in the system power waste caused by repeated cycle

4. The host has errors, bellows duct design into the grinding zone material before the larger particles and grinding crushed particles are often thrown into bellows gathered in worm tail, and extends forward and make the air volume gradually reduce, easy cause traffic jams, not powder powder or less, affect the production.
